The Arduino platform is distinguished by its flexibility and ease of use for the realization of open-source electronic projects. Since it is based on free software and hardware, creators and developers are supported.

One of the main types of projects that Arduino users implement are those based on the use of LEDs. Well, the learning curve for this element is easy and you can achieve great things in a short time.

In fact, software effects with LEDs for an Arduino project are interesting from scratch. In this article you will learn how to do that properly and what are the best Arduino kits for that.

What are the best Arduino kits for programming LED effects?

To begin building a project that focuses on programming effects with LEDs, the basic hardware needed is an Arduino kit, which simplifies the process.

Here are some of the best options:

UN starter kit

Not only is it an ideal kit for learning C++ programming and basic electronics knowledge, but it’s also worthwhile for programming LED effects from scratch. As such, has all the necessary equipment in the box.

You will find among its components : Arduino UNO card with ATmega 328 chip with connector for easy removal, 8 √ó 8 LED dot matrix, RGB LED with holder, 5 red, 5 yellow and 5 green LEDs. For example: USB cable, 16√ó2 display with I2C interface, 16-key keypad, water/rain sensor, servo motor with accessories, 5V DC motor with fan, etc.

Mega Starter Kit

This is the Arduino starter kit, which, in addition to traditional elements, includes other additions that significantly expand the possibilities and ensure a more complete user experience. So it can be used for programming LED effects, but also for other electronic projects.

When highlighting your materials, we mention: Arduino-Mega-Board, external power supply, 5 red LEDs, 5 blue LEDs, 5 green LEDs, 5 yellow LEDs and 5 white LEDs. In addition to 8 √ó 8 LED arrays, sensors for light, temperature and humidity, water and rain, motion and distance, capacitors, transistors, 10-pole/polymer cables, 65-pole/color cables, etc.

Basic kit for Arduino

This is another beginners kit to learn how to work with the Arduino platform. Its importance lies in the fact that it allows you to create different projects thanks to the variety of components included.

Next, we will mention the main elements included in the Basic Kit for Arduino : Bulletin board 830, 5 red LEDs, 5 blue LEDs, 5 yellow LEDs, 1 RGB LED, LED module 1√ó4 seconds, LED module 1√ó7 seconds, LED matrix 8√ó8 points, 4 push buttons, IR remote control, temperature sensor LM35, 2 ball sensors, various resistors, various dupont connection cables, etc.–ī.

Learn step by step how to program LED effects for an Arduino project

The effect with the LEDs of the Arduino project is to program a specific sequence that makes these lights go on and off at specific intervals.

To do this, you should always use an Arduino card and proceed as follows:

Connecting the LEDs

To create the effect, use 5 LEDs and connect them to pins 2, 3, 4, 5 and 6 of the circuit board. It is important to ensure that the correct resistor is installed for each LED, taking into account Ohm’s law (V = I * R).

When the voltage is z. B. 5 V and between 5 mA and 20 mA must reach the LED, so it makes sense to use a resistor between 250 and 1000 Ohm. The wiring diagram will then look like the figure.

Controls the speed of LED.

From the previous installation, it’s time to add a potentiometer to control the speed of the effect with the LEDs. To do this, add to your code at the beginning of the loop (): time = analogRead (A0). The speed of the LEDs can thus be read at the analog input of the potentiometer used. In the picture we see how the potentiometer is connected.

Try other attractive effects

Using the circuit in this image, it is possible to test and/or program other effects with LEDs in an Arduino project by simply changing the code in the program.

The code in question is as follows:

*/

int pinArray [] = [2, 3, 4, 5, 6, 7] ;

int score = 0 ;

internal timer = 100 ;

empty parameter () {

// …hacemos todas las declaraciones a la vez…

for (account = 0; account < 6; account +++) {

pinMode (pinArray [score], OUTPUT) ;

}

}

empty loop () {

// Timer = Analog readout (A0); // Value on analog readout and timer

for (account = 0; account < 6; account +++) {

// Timer = analog reading (A0) ;

digitalWrite (pinArray [count], HIGH) ;

back (timer) ;

}

for (count= 0; count< 6; count++) { // timer = analogRead (A0); digitalWrite (pinArray [count], LOW); return (temporizador); } for (count= 5; count> = 0; count–) {

// Timer = analog reading (A0) ;

digitalWrite (pinArray [count], HIGH) ;

back (timer) ;

}

for (count = 5; count> = 0; count–) {

// Timer = analog reading (A0) ;

digitalWrite (pinArray [count], LOW) ;

back (timer) ;

}

}

A list of the best Arduino LED projects you can do yourself to practice

To learn more about Arduino, it is recommended to carry out certain projects with LEDs, which are the optimal input method due to their ease of use.

Therefore, for practical purposes, you can refer to the following qualified examples:

LED Ballast Sealing

Comes with an easy to install LED bar that enhances your ability to respond to sounds, especially the rhythm of music. To this end, it contains a microphone that captures sounds and transmits the information to the Arduino platform to be displayed by a combination of brightness control and tape.

We need you on this project: Arduino Nano R3 board, LED strip WS2812B, single turn potentiometer (10 kOhm), microphone and amplifier, 12 V 1.5 A DC power supply and 5 V DC converter.

AmbilightLantern available

Ambilight is a backlighting system that adjusts the contrast in a room. With an Arduino, you can build such a home environment that is able to analyze and detect changes in the color of the source, and respond to the TV or monitor as the ambient light does.

If you want to make an absolutely cheap Ambilight system with an Arduino, you should use the following : Arduino uno board, 5 meters WS2812B LED strip, double sided tape, 5V power supply and computer installed processor. In this case, each LED has its own chipset and one line is used for communication.

Playroom with LED guns

This is a toy gun that emits invisible infrared light via an IR LED. This means that the light from the LED comes out at a wide angle, which makes aiming much easier for the user. This fairground attraction can be built cheaply with an Arduino.

To make the light emitted by the LED gun unique, it is recommended to program the element’s microcontroller to turn the LED on and off every 38 kHz (38,000 times per second); when the target’s microcontroller detects this signal, it activates a servo motor that helps to drop the same.

Domino Clock

This is an elegant and original domino clock. The method is that the first card in the row shows the hour, while the other two cards show the minutes. In other words, a total of three dominoes are imitated.

It requires, among other things, the following elements: Arduino nano panels, LED lights, 3mm MDF panel, 3mm translucent smoke grey acrylic panel and 3mm white acrylic panel. To make the light brighter, you can adjust the intensity of the LEDs according to the ambient light conditions of the object.

Greenhouse

With an Arduino you can also build a greenhouse to measure temperature, humidity and light to keep your plants in the best conditions. It is characterized by the fact that it guarantees their well-being regardless of the outdoor environment, so it can be installed anywhere in the house.

As for operation, stepper motors controlled by the Arduino board open the top panel and turn on the greenhouse lights to water the plants. That’s why it can give so many visual and audible warnings. His material: A 5 mm red LED, a 5 mm green LED, an LED light, an Arduino Uno board, three resistors, a buzzer, a motion and temperature sensor.

If you have any questions, leave them in the comments. We will get back to you as soon as possible, and that will certainly be of great benefit to more members of the community. Thank you.
